@Lee re voltage measurements:

Driven from my RavPower (unrecommended battery)
Pi 3B
Single SDR 4.94V throttling 0x0 (none) - measured before the two SDR test.
Two SDRs 4.82V Throttling changing between 0X5000 (throttling has occurred) and 0x50005 (being throttled)
Single SDR 4.94 Throttling 0x0 - measured after the 2 SDR test in case of battery fade!

The voltage was measured with a DVM off the solder pads under the Micro USB port after the hotspot was active and the client connected to view home screen.

Hi Lee, yes it was a V2 ordered from RTL-SDR, they look identical to apart from the PCB colour!

thanks Adi

Hi Lee, no, no one recommended the RavPower I have used it for sometime since the internet of things radio board days...

For me I have a V2 purchased directly sometime ago and the one in the Rosetta upgrade kit.

On boot from the non recommended battery throttling is 0x0 shortly after it is 0x50005
Removing either SDR and throttling remains 0x0

On a genuine rpi mains supply and with both SDRs throttling remains 0x0

Peter, which battery pack do you use?

Also where are you picking up the 5v for your fan?

Last question
Do you think the more efficient power supply in in the 3B+ will overcome some of these issues when it’s suppoted?

Ok so here are my non scientific findings!
I have two battery packs one states 2.4A out the other 2.1 cpu shows throttled hex 50005 under voltage.

Plug pilotaware into a pi mains supply OxO so all ok

Plug the Pi into a 3A mains usb supply using the same cable as with the battery packs 0x0

Using a different 20awg cable with original battery 0x50005

So looks like only certain battery packs will do and my Rav packs are not good enough 😭

I wondered what that was! I’m using a 20swg short cable and a 2.1A battery pack!

These are the ones I ordered https://www.aliexpress.com/item/SMA-TS9-Adapter-SMA-Female-to-Y-type-2-X-TS9-Male-Connector-Splitter-Combiner-Cable/1000001913663.html

Make sure you select the RG316 option for the SMA to MCX

Well, my cables arrived today for my Pilotaware and that of a friend.

I found they seemed to fit ok so long as you have the cables parallel to the board.

So that's two more Pilotaware's that can receive weather now to fly somewhere that transmits it! guess the cost and ability to join the transmission of weather trial as a ground station is costly?

thanks for the replies and the confirmation.

Hi all,
      I ask for a friend, no honestly, I have already upgraded via the rosetta DIY kit.

Will the old bridge board work with the latest image and a Pi 3B ? I realise the license number will need changing.

If so what are the advantages:
     Faster process thus handling multiple connections better and processing of mode C contacts?
     Integrated WIFI, one less dongle?

Disadvantages (if any)
    Greater power drain?


thanks Adi

cool, I look forward to floating without the aid of any "substances"!
